I just finished this beautiful 545i with gray leather interior that had brown belt marks on the driver's seat.
Rather than strong chemical cleaners (which could damage the leather dye), I resorted to a mixture of 8 parts warm water to 2 parts mild dishwashing soap. I used a boar's hair brush to scrub the seat faces and a terry cloth towel to remove the solution. It took a couple of tries, but the brown belt leather stain came out. You might try that combo/brush.
Here's a pic of the finished car.
